A magnetically-separable H3PW12O40@Fe3O4/EN-MIL-101 catalyst for the one-pot solventless synthesis of 2H-indazolo[2,1-b] phthalazine-triones

A magnetic inorganic-organic catalyst, PTA@Fe3O4/EN-MIL-101 (EN = ethylenediamine, PTA = phosphotungstic acid) was fabricated and characterized by XRD, HRTEM, FESEM, UV-vis, TGA-DTA, FT-IR, XPS and porosimetry. PTA retained the parent Keggin structure upon dispersion throughout the amine-functionalized chromium terephthalate metal-organic framework, over which magnetic Fe3O4 nanoparticles were previously introduced. The resulting composite heterogeneous solid acid was an active catalyst for the one-pot synthesis of diverse 2H-indazolo[2,1-b] phthalazine-triones in good -> excellent yields under mild, solventless condition, and offers facile separation and excellent recyclability.

Recycling of high temperature steam condensed water from petroleum refinery by thermostable PPESK ultrafiltration membrane

The purification and reclaiming of synthetic and industrial high temperature condensed water containing excess oil and iron is investigated in this study using thermostable poly(phthalazine ether sulfone ketone) (PPESK) ultrafiltration membranes. The results show operation parameters such as transmembrane pressure, temperature and pH of feed solution, initial oil and iron concentration each play important roles in the permeate flux and oil/iron removal efficiencies. Membrane performance is almost recovered after washing with a combination of NaOH and ethanol. High temperature condensed water from Daqing petroleum refinery can be consecutively purified using a PPESK ultrafiltration membrane. The turbidity of the solutions is almost removed. Oil and iron concentrations in the permeate solutions are below 1 mg/L and 50 mu g/L, respectively, which satisfy the Quality Criterion of Water and Steam for Steam Power Equipment in China. UF process shows a promising alternative to existing technology in the Daqing petroleum refinery in terms of cost and environmental protection as well as energy recovery. For future possible combination of UF and NF process application, both economic cost and saving are evaluated, and the breakeven time is about 11 months. (C) 2013 Elsevier B.V. All rights reserved.

Synthesis of new (trifluoromethyl)-1H-benzo[e][1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo[5,6][1,2,4] triazino [1,2-b]phthalazine-8,13-diones

In this paper we investigated reactions of urazole and phthalazine with N-(aryl)-2,2,2-trifluoroacetimidoyl chloride derivatives. Results showed that when imidoyl chloride derivative has a fluorine atom at ortho position (3a-c), in two steps under a S(N)i mechanism and then SNAr reaction mechanism produce ay1-5-(trifluoromethyl)-1H-benzo [el [1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones (4a-c) and 6-(trifluoromethyl)benzo[5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones (4i,4j) in good to excellent yields. In the other imidoyl derivatives (3d-h and 3i,3j) under these conditions cyclization reaction does not occur and therefore produce 1-aryl-2,2,2-trifluorornethyl)-4-phenyl-1,2,4-triazolidine-3,5-diones (4d-h) and 2-(2,2,2-trifluoro-1-(arylimino)ethyl)-2,3-dihydrophthalazine-1,4-diones(4k,41) (non-cyclic products) in good to excellent yields.

Convenient Synthetic Route to Palladium Complexes of Unconventional N-Heterocyclic Carbenes Derived from Pyridazine and Phthalazine

Several Pd(II) complexes with unconventional pyridazine- and phthalazine-derived carbene ligands were synthesized via direct oxidative addition of Cl derivatives of the alkylated diazine heterocycles to Pd(0) species. The alkylated ligand precursors are readily prepared from commercial starting materials, and oxidative addition is regioselective. DFT calculations confirm that the thermodynamically favored products are formed. Four complexes (1-4) have been fully characterized, including by X-ray crystallography. Attractive intramolecular pi-pi stacking between the electron-poor N-alkylated diazine heterocycles and adjacent phenyl groups of the PPh3 coligands is revealed by the solid-state structures.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 90-64-2 is helpful to your research. Safety of 2-Hydroxy-2-phenylacetic acid.

Aromatic azaheterocycle-cored luminogens with tunable physical properties via nitrogen atoms for sensing strong acids

A series of luminogens comprising one pyridine, 1,3-diazine, 1,4-diazine, 1,2-diazine and phthalazine moiety as the central core and two AIE-active tetraphenylethene units in lateral positions have been readily synthesized by Suzuki cross-coupling. They exhibited remarkably different photophysical and electrochemical properties, as well as solid packing and fine controllability via the number and position of the nitrogen atoms in the aromatic azaheterocycle core. Among them, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed strong AIE activities, whereas the 1,2-diazine and phthalazine-cored luminogens exhibited almost no AIE effect. The intrinsic Lewis basicity of the as-prepared luminogens endowed them with the ability to fluorometrically detect acids with different pK(a) values. When protonated by a strong acid such as trifluoroacetic acid, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed relatively weak AIE effects. In contrast, the 1,2-diazine and phthalazine-cored luminogens exhibited highly sensitive responses to strong acids within a precise pKa range by displaying turn-on fluorescence emissions in the low-energy region, which was probably owing to the synergetic effect of AIE and the constraint of the intersystem crossing effect upon protonation of the 1,2-diazine segment. They displayed reversible acidochromism in response to protonation and deprotonation in the solid state. Such unique properties of the as-prepared luminogens could be used for the selective discrimination of some organic acids, which is highly valuable in the study of biological metabolism.

Genetic variants of aldehyde oxidase (AOX) 1 in cynomolgus and rhesus macaques

The cynomolgus macaque is a non-human primate species widely used in drug metabolism studies. Despite the importance of genetic polymorphisms in cytosolic aldehyde oxidase (AOX) 1 in humans, genetic variants have not been investigated in cynomolgus or rhesus macaques. Genetic variants in AOX1 were identified and allele frequencies were assessed using the genomes of 24 cynomolgus and 8 rhesus macaques. The analysis identified 38 non-synonymous variants, some of which were unique to cynomolgus macaques (bred in Cambodia, Indochina, or Indonesia) or rhesus macaques, whereas many variants were shared by the two lineages. Among the variants observed at relatively high frequencies, eight were selected for functional analysis. Recombinant P605L and V1338I AOX1 variants showed substantially lower phthalazine and carbazeran oxidation activities than the wild-type AOX1 protein. In liver cytosolic fractions from cynomolgus and rhesus macaques genotyped for P605L and V1338I AOX1, groups of cytosolic fractions with P605L and/or V1338I AOX1 variants showed significantly lower phthalazine and carbazeran oxidation activities than the wild type. These results indicate that AOX1 is polymorphic in cynomolgus and rhesus macaques, just as it is in humans. Further investigation is needed to reveal the functional significance of these AOX1 variants in drug metabolism.
